This paper proposes the torque and flux feedback control of an induction motor using a discrete state observer which estimates the secondary flux The derivation of the observer based on digital control theory is presented. The magnitudes of the generated flux and torque evaluated by the estimated secondary flux are applied to the feedback control. The configuration of the feedback control System is presented. The robust performance of the proposed system against the secondary resistance variation is validated by the simulation and experimental results in the paper.
